ABSTRACT:
An Ethernet PHY hardware device supports Ethernet MAC SDH/SONET Automatic Protection Switching (APS) functionality for managing protection from failures and recovery from failures on an Ethernet network. An Ethernet PHY sublayer stored on the Ethernet PHY hardware device is configured to monitor working and protect channels and generate an interrupt upon detection of a hard failure or a soft failure. Upon detection of port failures or link failures, the Ethernet PHY sublayer generates the interrupt to invoke an Ethernet MAC Client APS Controller configured to generate and terminate APS requests on working and protect channels to manage protection of working and protect channels from failures and recovery from failures on the Ethernet network. The Ethernet PHY hardware device is configurable for use with a plurality of different network topologies to manage protection from hard or soft failures and recovery from hard or soft failures on the Ethernet network using the Ethernet PHY sublayer.
